MOTOR.

SPECIFICATION forming parbof Letters Patent No. 349,758, dated September28, 1886.

Application filed April 38, 1886.

To ail wwm 'it may concern:

Be it known that I, RENALDO SOLANO, late of Sau Francisco, in the Stateof California, but now of Brooklyn, in the county of Kings and State ofNew York, have invented certain Improvements in Vacuum-Motors, of whichthe following is a specification.

This invention relates to that class of motors in which a to-andfro orreciprocating movement is given to a piston through the agency ofatmospheric pressure induced by thealternate withdrawal from andadmission to of the atmosphere from behind the piston.

The object of my invention is to provide Aa x 5 motor of the classmentioned which will afford greater strength and durability, be capableof more easy repair, and more certain and effective in its operationthan those heretofore in use.

My invention comprises certain novel combination of parts whereby theseobjects are eff'ectually secured.

Figure l is a central longitudinal sectional view representing my saidinvention with the piston at the end of its outward stroke. Fig.

2 is alike view with the piston shown at the end of its inward stroke.Fig. 3 is a face or front view of the same.

A is the cylinder. On the front or forward periphery of it is a radialflange, e. At its 3o opposite or near end is thepassage b, which, by

a suitable pipe or other means, is connected with any ordinary orsuitable apparatus for alternately exhausting and supplying air to saidcylinder. As such exhausting and sup- 3 5 plying devices are wellknown,i it is unnecessary to here describe the construction or operationthereof.

Provided in or to the cylinder Aand preferably integral therewith, areguides c.

B is the piston. This piston has its circumference adapted to move ineasy contact during its stroke with the internal surface of thecylinder. There is a cylindrical ange, j, on rthis piston, whichaugments its circumferential bearing-surface in contact with thecylinder, as aforesaid, and also affords a seat for the inner edge ofthe iieXible diaphragmpacking C, which consists of a web of leather,sheet indiarubber, or other iiexible material 5o practically imperviousto the passage of air.

Serial No. 200,456: (No model.)

The office of this diaphragm-packing is to Y connect the piston to thecylinder in a prac` tically air-tight manner, and thus pack the -jointbetween the piston and the cylinder.

The outer edge of this diaphragm-packing rests 5 5 upon the liange c ol'the cylinder. A iiat ring, D, is laid upon the said outer edge of thediaphragnrpacking and the ring. The flange a and the circuniii'erentialouter part of the diaphraginpaeking are snugly held together 5c by thebolts g, the diaphragm-packing being tightly and securely held betweensaid ring and flange, and thereby secured to the cylinder A. An annulus,E, is fitted upon the inner circumference of the diaphragm-packingwithin the ilange tf and bolted to said flange by bolts h with thecontiguous inner circumferential portion ot' the diaphragm-packingclamped between said annulus h and iiangef, thus securing the saiddiaphragm-packing to 7o the piston. The piston has guide-rods m, whichextend through the guides c, and the oflice of which is to assist inmaintaining the piston in' proper axial position within the cylinder.Nithin the cylinder, and preferably placed around the guiderods m, aresprings a, ar- A ranged to tend to move the piston forward or outwardwhen said springs are permitted to'act after compression. To the frontor outer side of the piston is duly pivoted or otherwise at- 8o tached arod, F, or other device for transmitting motion from the piston. Thenair is exhausted from the cylinder A,the pressure of the outeratmosphere forces the piston inward. W'hcn air is readmitted to thecylinder, the 85 piston is enabled to resuni'eits place by the action ofthe springs a, or if air under more than atmospheric pressure is forcedinto the cylinder the piston will be moved outward with a forceproportioned to the degree to which the 9o internal pressure exceedsthat of the atmosphere.

My said invention is especially adapt-ed for use under conditions whichimply the necessity of considerable power applied with a shortpiston-stroke; but my said invention may be used for various purposesindependent of such conditions.

The apparatus may be very readily taken apart for repairs, examination,or the like. 10o

I am aware that it has been proposed to transmit motion from a diaphragmfitted upon a suitable vessel and acted upon by the alternate exhaustionand supply of air to and from said vessel, said diaphragm beingre-enforcedvnear its center by an annular plate; but such constructionand the operation therein are different from my said invention, whichlatter includes the use and operation of a piston Working in contiguityto the inner surface of the cylinder and connected by a flexible web ofany suitable material with the said cylinder in such manner as to packthejoint between the periphery of the pist-on and the concentric innersurface of the cylinder, and which web I term for convenience ofdesignation a diaphragm-packing.

It will be observed that by having` the diaphragm-packing attached tothe periphery of the piston the inward movement of the latter tends tobring the diaphragm-packing parallel, or substantially so, with theinner surface of the cylinder, so that the external air pressing in alaterally outward direction upon the packing-diaphragm tends to pressthe latter against the inner surface of the cylinder, and thus moreeffectually packs the piston against the ingress of air.

That I claim as my invention, is-

l. rIhc combination of the cylinder A, having the iiange a, the pistonB, having` the flange f, the diaphragnrpacking C, and bolts g and h, theWholearranged for joint use and operation substantially as and for thepur pose herein set forth.

2. The combination of the cylinder A, the piston B, having itscircumference contiguous to and coincident with the inner surface of thesaid cylinder, the diaphragm-packing O, connecting said piston With saidcylinder, the guides c, and guide-rods m, substantially as and for thepurpose herein set forth.

3. The combination of the cylinder A, piston B, having its circumferencecontiguous to and coincident with the inner surface of said cylinder,the diaphragm-packing C, connect ing said cylinder and piston, theguides c, guiderods m, and springs a, all substantially as and for thepurpose herein set forth.
